Hi @StaffanMelin, This sounds like a fun project. I would recommend also opening a discussion in https://github.com/cardonabits/haxo-hw/discussions where you might get feedback from more hardware-oriented folks. My recommendation on hardware selection would be that it is easy to source. If you want people to contribute, the hardware should be cheap and widely available. Also, if you stay in Rust you will not introduce language barriers to those already familiar with So why not stay with a Raspberry Pi Zero? They are cheap, widely available, familiar to most haxophonists and small enough to fit on a foot pedal. In fact there are several guitar foot pedals that use it: 1 2 ... or even the RPI4 3 Looking forward to see what you come up with! |

I see. In that case I would just ask you to consider an option that be programmed in Rust. I've been programming STM32s in Rust for some time now, and never missed my C/C++ days... |

So the prototype hardware is finished as a simple ... prototype! :) It is powered by the inexpensive yet powerful Seeed Xiao (SAMD21 version), chosen because a) it has good connectivity b) I already had one. :) I also had some pieces laying about from a previous controller project so I simply put them together and connected them up to the Xiao. Well, I had to replace the two pots on the mod and pitch wheel (that I salvaged from a broken keyboard in my common garbage room).
Future plans include connecting a small OLED over I2C, as well as a simple analog button combo, so I can build a simple interface on the Xiao. Then the ports of the Xiao are all but taken. All in all, pretty standard stuff, readily available. I hope to have a working example this weekend. If I find it useful, I will add documentation and code (I will anyway! :) ). I hope to be able to use the 2, 3 and 4 with my feet, we'll see. Whatever, the important thing is having some kind of analog input and get it to the Raspberry Pi on the haxo. I call it the "Hexo"! :) |

Hi @StaffanMelin , thank you very much for sharing your project! I am interested to do some sort of remote control like your foot pedal as well. My idea is much simpler. I have a Seeed Xiao left over.
So my questions about your project are the following:
Thank you very much in advance! |

Hi @StaffanMelin, I pushed my first steps here: https://github.com/stardusthamster/haxo-misc/tree/main/misc So if you want to take a look. But it is still work in progress... |

How is it going?
I don't know Rust unfortunately, but it looks a bit like C++. One day I
have to learn it, it seems to get a lot of traction.
Anyway, good luck!
Staffan

So I am thinking of making a foot controller for the Haxo.
initial thoughts and ideas
Making it
Any thoughts?
